Duender MGN12H Edition

My take on the Duender by Sergei Irbis. This version uses MGN12 linear rails with H size bearing blocks and adds mounting points to use end stops if you prefer those to sensorless homing.

For the configuration I used, you will need the following lengths of MGN12 rail:

2x 300 mm for Y

1x 300-320 mm for X

3x 350 mm for Z

If you are using endstops, your hot end will need something to reach the X endstop on the top left gantry mount and something to reach the endstop on either the left or right XY motor mount. If you are using sensorless homing or decide to mount your Y endstop elsewhere, you can use the XY motor supports without an endstop mounting point.

The toolhead I designed for my duender limited how far back my toolhead could travel, so my version of the bed mount pushes the bed pretty far forward, so your toolhead may not reach the front of the bed depending on how far forward from the gantry your nozzle is. The nozzle must be a MINIMUM of 29.5 mm from the center of the nozzle to the face of the linear rail and a MINIMUM of 31.5 mm from the tip of the nozzle to the underside of the gantry extrusion in order to use my bed mounting solution.

If you would like to modify the files, or see how things go together they can be found here.

If you have any questions, I can be reached either in the comments on this model, or in Sergei's discord server.
